*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Birkenhead is located on the Wirral Peninsula, directly across the River Mersey from Liverpool, meaning its coastline is exposed to the waters of the Mersey Estuary and the Irish Sea. The water temperature of the Mersey here is typically quite chilly year-round, ranging from a winter low of around 5.5∘C (42∘F) in February to a summer peak of approximately 17∘C (63∘F) in August. This relatively cool range means that wetsuits are highly recommended even in the warmest months.
Open water swimming in the River Mersey itself near Birkenhead is generally discouraged due to strong tidal currents, heavy commercial boat traffic, and persistent, although improving, water quality concerns related to sewage overflows. Instead, local swimmers often use more controlled environments like the dedicated open water swimming venues in the nearby docks or the Marine Lake at West Kirby for safer activity. For other recreation, Birkenhead offers the historical Birkenhead Park, the inspiration for New York’s Central Park, as well as the ancient Birkenhead Priory, the oldest building on Merseyside, and the Williamson Art Gallery and Museum.
